you can look at swamps writeup for locking the tc... or spend 400 bucks on a controller.

 

I followed these directions with the DPDT switch and I must say I am very happy with it. I like when im driving in the mountains that I can throw the switch to work with the brake and save my tranny. Also the 2.5amp diode is a little overkill but it does not matter. Its only blocking current form flowing back through to the brakes. This is only a problem when the EBPV is under normal operation. With this set up you have the option to switch back and forth between on and off as well as working with the brake . it took me about three hours, I double checked everything and the directions were good except for the changes I stated in the other post. I would recommend doing this to the next guy because it is super handy. good luck

Gradyc,
That's what I was thinking, a DPST switch, One pole for ground to T/C, and one pole for energizing the EBPV. So double pole, with one operation activating both, so single throw
DPST... right?

Can you look at my diagram from my previous thread and tell me what you think? On next post as well.
Just want to confirm with someone if I'm proposing to do what I want and will get the results I want from this schematic.

Thanks for the tips Hosser, that's getting me closer to actually doing this thing.
Can you look at one of my previous threads and see the schematic I've drawn for a DPST switch (which basically only uses the "Brake lights" option of swamps)? If you could see if this would work, that would be awesome.. or encouraging at least. Check my next post.
What I want to do is just use the brake lights option, so basically energizing the EBPV and grounding the T/C in one operation, so I would just use a DPST switch right?

Also, how much voltage operates the EBPV? Full 12V?

Basically I want to just have ON/OFF (locking t/c and energizing EBPV, not interested in swamps DPDT switch, although I could use it but would just not hook up the 12V always on portion, so it would be ON/OFF/OFF with his option.

What do you think?

Thanks in Advance

EBPV & TC lock DPST switch[1].pdf

Check this out.... Do you think it will work?

 

I tried this and could not get it to work. The wire from PCM to EBPV has voltage any time the key is on. How does applying voltage to a line that already has voltage help anything?

Thanks

 

Maybe try waiting until your engine warms up. It's probably getting voltage during start up.

If I disconnect it from the PCM and just use an on-off switch. Would it make any problems??

THANKS

 

What size fuse for the supply power?

 

I couldn't open the file with the write up. I am not sure witch diodes i need to buy please help!

 

Good info im gonna look into it
